How to set up DNS records on gandi.net to use a custom domain on Github Pages

You would think it would be easy to find this information, but none of the Github or Gandi documentation is clear so I have recorded the required steps here.

Create the following A records:

@ 1800 IN A 185.199.108.153
@ 1800 IN A 185.199.109.153
@ 1800 IN A 185.199.110.153

This query is to find geolocation of an IP address including latitude, longitude, city and country.

Legacy SQL doesn't support range conditions such as BETWEEN when using JOIN, so we need to filter data by WHERE. This means if IP address does not match any of the data inside geolite_city_bq_b2b, records will not be able to receive.

Use Standard SQL if you want to receive records no matter you succeed to find geolocation or not.

Please refer to the following post for more detail.

Revert / Undo a Gist Commit

It was not exactly obvious. Here's how to revert a Gist commit!

Checkout the gist like a normal git repo:

# replace the Gist ID with your own
git clone [email protected]:cc13e0fcf2c348cc126f918e4a3917eb.git

Treat it like a normal repo. Edit, force push, etc.

How to convert markdown to PDF:

This post reviews several methods for converting a Markdown (.md) formatted file to PDF, from UNIX or Linux machines.

Using `Pandoc`:

	# Often when reading in a ShapeFile from Basemap, you'll get: "ValueError: readshapefile can only handle 2D shape types"
	# A trick can be to convert your geometry in your GeoPandas Dataframe and restoring the new flattened 2D geometry
	# series back into a shapefile and try again.
